Rafael J. Wysocki 436ce71638 [PATCH] Revert "swsusp: disable nonboot CPUs before entering platform suspend" 
This reverts commit 94985134b7 and
insteads removes the WARN_ON() that caused that commit in the first
place.

The problem is that we call disable_nonboot_cpus() in swsusp before
powering down the system in order to avoid triggering the WARN_ON()
in arch/x86_64/kernel/acpi/sleep.c:init_low_mapping() and this doesn't
work well on Thomas' system.

So instead, remove the WARN_ON() in arch/x86_64/kernel/acpi/sleep.c:
init_low_mapping(), which triggers every time during the suspend to disk
in the platform mode, as the potential problem it is related to doesn't
seem to occur in practice.

[ I think we might want to disallow the case of multiple users of that
  mm, or something.  Normally, playing with the current process page
  tables on the current CPU should be fine as long as we don't have
  other threads using those tables at the same time..

  Anyway, not pretty, but better than the warning or the lockup - Linus ]
